Introduction
The DigiTag-LR Receiver is designed to be used with the DigiTag-LR range of active transmitters from the CDV
Group. Best performance from the transmitter and receiver will be gained when adhering to all the relevant
instructions. The DigiTag-LR receiver will read and decode the secure coded signal from the transmitter when in
the field range of the receiver, and convert this in to a format for access control units to validate. The DigiTag-LR
Receiver is equipped with a low / high gain selector and a range attenuator for further detection range reduction.
The exact range is dependant on environmental conditions, mounting proximity to metal objects and battery
condition of the transmitter. The DigiTag-LR receiver contains an internal antenna that must not be modified as it
is tuned for best performance. It must always be mounted upright and clear of metal obstacles or mountings.
The system fully complies with European Directives 73/23/EEC, 89/336/EEC, 99/05/EC, the FCC Part. 15
Regulation and Industry Canada RSS-210 Radio Standard Specification.
